Smallest writing possible

by ARTiFactor on Oct. 19th, 2008

What is the smallest writing possible?

I cannot imagine writing smaller than if the letters are composed by arranging individual atoms.

An Osaka University research team has demonstrated an “atomic pen” that can inscribe nano-sized text on metal by manipulating individual atoms on the surface.

The completed text measures 2 x 2 nanometers. The procedure is described in the October 17 edition of Science magazine; "Complex Patterning by Vertical Interchange Atom Manipulation Using Atomic Force Microscopy"
